They offer software "free" but charge about $6 per item for S&H. It's still a good deal if they're reliable. Has anyone heard of them or used them? I'd like to find out more before I consider ordering - if they're scammers I'd just as soon keep my $6.

$6 is comparable to what everyone else is charging for equivalent software, and I doubt they'd go to all the trouble of setting up the site so they can scam a few dollars. There are far easier ways of scamming people out of money. You may also note that they have a genuine Verisign seal, and that Google doesn't seem to bring up any pages from people complaining that they were cheated.
